IMPROVEBEENT -INAG-OVERNORS FOR STEAM A-ND OTHER ENGINERY.

The Schedule referred to in these Letters Patent and making part of thesame. v

To all whom it may concern Be it known thatI, J osnrn THEoDon Losser, ofWrzburg, in the Kingdom of Bavaria, have invented a new and usefulImprovement in Power-Regulators; of which the following. is a full,clear, and exact description, reference being had to the accompanyingdrawing, forming part of. this specication, in which- Figure 1represents a sectional elevation of a powerregulator constructed inaccordance with my improvement, and

Figure 2, a plan of the same.

Similar letters f reference indicate corresponding parts.

This, my improved power-regulator, which is applicable as a governor tocontrol the throttle-valve of a steam-engine, and to other purposes,consists in a certain arrangement or combination of mechanism,

whereby, on rotary motion being communicated to a shaft from the engine,or other motor, said shaft, or spur-wheel carried by`it, is made vto setin rotary motion, by a pinion in gear with the spur-wheel, a secondaryshaft, hung on or to turn in a balanced or weighted lever, whichsecondary shaft carries arms provided with vanes, so that, on the speedof the motor being increased or diminished beyond the velocityt isrequired to move, anI increase or diminution of resistance is met withby the 'fan against the air, which ca uses the lever carrying thesecondary shaft to rise or fall, and in so doing to regulate, by an armand other suitable connections, the speed of the n1ctor, as, forinstance, by controlling the throttle-valve of an engine; and the4invention furthermore consists in la combination, with such anarrangement, of a shell or airvessel,`connected with the lever carryingthe secondary shaft, and open at its lower end, so that on immersion. ofthe openg end of the shell in a vessel containing water or bther fluid,said shell, by its expulsion of air from or within it, asV it rises andfalls, will 'serve to correct the too great sensitiveness of thegovernor or regulator.

Referring to the accompanying drawing, A represents a column carrying atable, B, on which are erected journal-boxes C '0, thatserve, directlyor indirectly, tof carry a horizontal shaft, I), which is `caused torevolve7 as indicated by the arrow zu, by or through a pulley, E, fromthe engine or other motor. This shaft I) carries a spur-wheel, F, whichgears with a pinion, Gr, fast on a shaft, H, which has its bearings in alever, I, that is free to vibrate or turn on the shaft D, and that,. byanextension-of its collar,

or bearing through the one journal-box C, carries an arm or lever, J,from which connection may be made tc'regnlate the throttle-valve of theengine or other device controlling the speed of the-motor.

- `The lever I has adjustable on it,` at its pinion-end, a weight, K,and if desired, a similar weight may be applied to the opposite end ofsaid lever, while the pinion-shaft H, which runs in said lever, eariiesarms L, having any desired number of vanes a. Connected with theopposite end cf the lever I, to which is the pinion G, is a shell, M, ofan inverted-bucket form, being open below and closed above, or havingits communication above, with theoutside air, established and regulatedby a cock, b. This air-shell or vessel is partially immersedin avessel,N, containing water or otherl suitable fluid.

From this description it will be seen that the ,lever I, being balancedor set by the weight or weights on the end or ends of it, to occupy afixed or certain position,

when the wheel F is rotated in direction of the airow x, at a velocityas acquiredl om the engine or motor, when running at its regular ordesired speed, no motion of the lever J takes p lace to move thethrottle-valve or other device, so as to alter the velocity of the engine or motor, but, supposing the latter to be .unduly quickened, thenthe increased resistance, as encountered bythe vanes a of the arms Lagainst the air, causes such a pressure or resistance to be thrown uponthe pinion G, in its `gear with the wheel E, as that the pinion-end ofthe lever I is raised, and the lever -J moved to act, say, upon theVthrottle-valve of the engine in such manner as to check the speed of thelatter. l Ou the other hand, a lowering ofthe speed of the motor,causes, by the diminished resist ance encountered by the vanes c, of thearms L, the pinion-end of the lever I to fall, and so tov open thethrottle-'valve to quicken and adjust the velocity of the engine. Theair-bucket or shell M, as -it is raised or lowered by the action of thelever I within the uid in the vessel N, serves to operate as a checkagainst too great sensitiveness on partof the regulator, and by theadjustment ofthe tap er cock b, so as to admit of av quicker or slowerexpulsion of air from the shell M, or more rapid or retardedsuctionthrough it, the action of the shell M, as a regulator ofsensitiveness, may be adjusted to the greatest nicety.

What is here claimed, and desired to beA secured by Letters Patent, is

l. The arrangement of the spun-wheel F, pinion G, weighted lever I, andvane-arms L, substantially as shown and described.

2. The inverted bucket or air-shell M, having an air-cock,b, 'and vesselN, in combination with the spur-wheel F, pinion G, weighted lever I, andvanearms L, substantially as herein set forth.

In witness `whereof, I have hereunto set my hand, this 25th day of July,1868.

'y JOSEPH THEODOR LOSSEN.
